Flashcards
Mitosis
Mitosis
A type of cell division that produces two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis
Meiosis
A type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell. These cells are unique and are used for sexual reproduction.
Somatic Cells
Somatic Cells
All body cells except reproductive cells, such as skin, muscle, and bone cells.
Gametes
Gametes
Reproductive cells, such as sperm and egg cells.

Recessive Allele
Recessive Allele
An allele that is masked (covered up) when a dominant allele is present. An organism must have 2 recessive alleles to show the recessive trait.

Homozygous vs. Heterozygous
Homozygous vs. Heterozygous
Homozygous: having two identical alleles for a trait (e.g., AA or aa). Heterozygous: having two different alleles for a trait (e.g., Aa).
